PATRICK VINCENT BRADY, OF NEW YORK, N. Y.

Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed October 19, 1905. Serial No. 283,417,

To all whom, it may concern:

Be it known that I, PATRICK VINCENT BRADY, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Umbrella-Rib and Stretcher Connection Therefor, of which the following is a full, clear, and exact description.

My invention relates to connections between the ribs of an umbrella and the stretchers, and particularly to the construction of laps for paragon umbrella-ribs.

The purpose of the invention is to provide a lap of simple yet durable construction and which can be stamped or otherwise produced from one piece of metal and which can be readily fitted to a paragon rib and clamped thereto and be practically concealed by the rib, and, further, to provide the complete lap with a knuckle within the groove of the rib, to which knuckle the stretcher is pivotally attached, permitting the stretcher to have all the required movements and to lie close in the groove of the rib when the rib and stretcher are in closed position.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a portion of an umbrella-rib and stretcher and the improved lap connecting the two. Fig. 2 is a transverse section drauni on an enlarged scale and taken practically on the line 2 2 of Fig. 1. Fig. 3 is an enlarged plan view of the lap. Fig. 4 is a plan view of the blank from which the lap is made, also drawn upon an enlarged scale; and Fig. 5 is a transverse section through the lap, taken substantially on the line 5 5 of Fig. 3.

A represents a paragon rib of an umbrellaframe, B a stretcher for such rib, and C the blank from which the improved lap is formed. The blankC (shown in Fig. 4) is made of metal as light as possible consistent with strength and consists of a central rectangular panel 10 of suitable length, having opposing projections 11 extending outwardly from its side edges, and at one end of the body 10 a longi tudinal slot 12 is made, while at the slotted end of the said body 10 opposing outwardlyextending ears 13 are formed, and in each of the said ears an aperture 14 is produced.

In producing the lap, which is shown in detail in Fig. 3, the body 10 of the blank is bent longitudinally upon itself, so as to form an inverted-Ushaped body 15, (shown best in Fig. 5,) and the side projections 11 are then bent upward and overthe said body 15 a desired distance, forming thereby side clamping-wings 16, and a space 17 is left between the opposing faces of the body 15 and the wings 16 of sufficient width to properly receive the longitudinal edges and adjacent side portions of the rib A, to which the lap is to be applied. WVhen the body 10 of the blank is bent to form the body 15 of the lap, as described, the slotted end of the body isarched correspondingly to the slotted portion thereof, and the ears 13 are then brought to a vertical position at right angles to the rib A, to which the lap is to be applied. WVhen a lap has been placed upon a rib A, as shown in Figs. 1 and 2, the cars 13, which then constitute knuckles for the lap, are practically within the groove of the rib A, and the flattened outer end of a stretcher B is intro-- duced between the knuckles 18 and is pivotally connected therewith by passing a pin 19 or its equivalent through the apertures 14 of the knuckles and a corresponding aperture in the stretcher.

The lap is held firmly in position on the rib A by simply forcing the clamping-wings 16 down to a firm engagement with the sides and upper side portion of the rib, as is shown in Fig. 2, and the opposing edges of the clamping-wings 16 may be brought as close together as may be desired, and while the shape of the clamping wings as shown is somewhat segmental the said wings may h'ave a different contour, if so desired.

The body portion 15 of the lap fits snugly to the Wall of the groove in the rib A, and the knuckles 18, as has been mentioned, are likewise practically concealed in the said groove of the rib, and all of the lap that is visible when it is applied to a rib are the wings 16.

This lap is exceedingly simple and strong and forms an effective connection between the rib and a stretcher, and it is evident that a lap constructed as set forth can be expeditiously and conveniently placed in position on a rib. 7

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A lapfor paragon umbrella-ribs,-com- 5 prising an arched body, ears at one end of the body, and clamping-wings which extend upward from the body. I

2. A lap for paragon umbrella-ribs, comprising an arched body adapted to fit into the groove of the paragon rib, clamping-wings at the sides ofthe said body, extending from its side edges upward over the crown portion of the body, which wings are adapted to engage with the outer face of the paragon rib when 15 the lap is fitted to said rib, and ears on the said body for attachment of a stretcher.

3. A lap for para on umbrella-ribs, comprising an arched bo y adapted to fit into the groove of a paragon rib, knuckles at one end of the body to pivotally receive a stretcher, and clamping-wings on the said body which are upwardly curved in direction of each other from the longitudinal edges of the body over the crown portion thereof, the said wings 2 5 geiig located intermediate of the ends of the 4. A lap for paragon umbrella-ribs, consisting of an archedbody, external clamping devices extending from .opposite sides of said 0 body over the top, and means for pivotal connection with a stretcher, said means being in a longitudinal plane with the said body.

5. In a blank for forming a lap for paragon umbrella-ribs, a rectangular body, opposing projections from the side edges of said body, 5 the body being provided with a longitudinal slot in one of its ends, and oppositely outwardly-extending a ertured ears located at the side portions o the slotted end of said body, for the purposes set forth.

6. The combination with a grooved umbrella-rib, and a stretcher having a flattened outer end, of a lap comprising an arched body adapted to fit into the groove of the rib,

clamping-wings at the sides of the body for 5 engaging the outer face of the rib, ears at one end of the said body and extending within the groove of the rib, the said ears receiving between them the flattened outer end of the stretcher, and means for pivotallyconnect- 5o ing the said end of the stretcher with the said ears.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

PATRICK VINCENT BRADY.
